Abstract

The mechanism has a take up cylinder and a master cylinder, with a fluid connecting line hydraulically connected between them. The mechanism has a screen body (2) with a central shaft (5) for pressure reduction and a spring (10) shaped guard ring loaded by pressure (8). At the base of the central shaft (11) a radial pitch circle opening (11) is arranged and the body and or the central shaft has a predetermined decrease of pressure when coupling the clutch during excess of a pre-determined volume stream of the inserted fluid. The body is movable when disengaging the fluid stream against a first block (7) of the housing (1) without pressure reduction. The body is movable when coupling against a spring-tensioned guard ring that an aperture is removed when a pre-determined volume stream is present.
